using utterances are called speech acts. There are some descriptive terms to label these utterances, such as apology, complaint, compliment, invitation, promise, or
request  1998:  47.  Speech  acts  consist  of  three  kinds  of  acts,  locutionary  acts, illocutionary  act,  and  perlocutionary  act.  Austin  in  Levinson,  1983:  236
describes these as: a
Locutionary act  : a sentence‘s utterance with a sense and reference. b
Illocutionary act  : an act of producing utterances with force or the speaker‘s intention.
c Perlocutionary act: the impact on the hearer which comes with the utterance
made by the speaker. In order to make the speech acts to be appropriate or succeeded in certain
circumstances,  there  are  conditions  which  must  be  existed,  namely  felicity condition. Yule 1998: 50-51 distinguishes five main categories of it:
a General conditions: the participants could understand the language which is
used and that they do not pretending to be someone, for example: acting. b
Content condition: the content of the utterances which talks about the future event.
c Preparatory condition: the understanding of the event whether it will happen
by itself, and has a beneficial effect or not. d
Sincerity condition: the speaker must be sincere when uttering the utterances. e
Essential  condition:  in  making  a  promise,  the  speaker  commits  to  do  what shehe  promises  to  the  hearer;  and  in  making  a  warning,  the  speaker  turns
herselfhimself from non-informing to informing about future event.
2. Conversation Analysis
The  interaction  by  two  or  more  peopleparticipants  who  cooperate, produce  some  utterances  and  respond  to  one  another  is  usually  called  as
conversation.  Levinson  states  that  conversation  happens  when  two  participants freely changing turn in speaking 1983: 284. It is the act of talking in sequence.
The  sequence  is  I  talk-you  talk-I  talk-you  talk.  The  participants  of  conversation take  turn  when  speaking  to  each  other.  The  sequence  or  the  structure  of
conversation  is  already  assumed  or  expected  by  the  participants  to  be  happened when they do the conversation. People use conversation for several uses, such as
exchange information, to tell stories, to buy  goods, to know other‘s feelings, to understand each other and other social or communicative event.
Conversation is somehow very complex. It could show its own order and
show its own sense of structure Schiffrin, 1994: 232. Thus, in pragmatics, there is a term called conversation analysis which analyzes how the conversations work
and reveals the conventions which conversation  has. The analysis is invented by Harvey  Sacks  along  with  Emanuel  Schelgoff,  and  Gail  Jefferson.  It  is  the
application of an approach called ethnomethodology. Conversation  analysis  analyzes  natural  conversations  or  actual  events
which  usually  happen in  people‘s  daily  lives.  Schiffrin  1994:  235  tells  that
conversation  analysis  focuses  on  the  details  of  real  events.  Furthermore,  this approach  tries  to  reveal  how  the  participants  of  the  conversation  are  able  to
produce  clear  utterances,  and  how  they  could  interpret  the  utterances  of  other people or participants Nunan, 1993: 84. Conversation analysis also tries to help
other  people  to  have  a  clear  sense  or  understanding  of  what  the  participants  are talking to each other. To do so, the notion of context is needed. Schiffrin  1994:
235 states that utterances always have contextual relevance for one another in a conversation.
Schiffrin,  Tannen,  and  Hamilton  2001:  253  claim  that  the  conversation
analysis focuses on the finding of the patterns which people oriented themselves
and  each  other  to  some  underlying  organization  of  talk.  There  are  some mechanisms  or  organizations  which  conversation  analysis  studies.  Those
mechanisms are especially about turn taking, constructing sequences of utterances across  turns  adjacency  pairs,  identifying  and  repairing  problems,  and  how
conversation  works  in  different  conventional  settings.  This  research  deals  with turns happen in a conversation and adjacency pairs, thus, the next sections would
discuss further related to both theories.
3. Turn Taking
In a conversation, people do not talking at the same time, but they wait for their turn to speak. The participants have the right to speak but they need to know
when is they turn to speak or when they have the ‗floor‘ of the conversation.  Yule 1998:  71-72  gives  an  analogy  of  conversation  as  a  market  economy.  In  this
market, there is a scarce commodity called the floor, or the participant‘s right to
speak. When the participant have the control of the floor, it is called a turn. In a situation,  where  control  is  not  yet  arranged  in  advance,  anyone  could  attempt  to
get control; this is called turn-taking.
Turn  taking  is  a  principle  which  could  rule  who  gets  to  speak  in  a conversation Wardaugh, 2006: 298. Through turn taking, the participants of the
conversation  could  manage  the  cooperation  in  conversation  Cutting,  2002:  29. The  first  speaker  of  the  conversation  needs  to  give  some  time  for  the  second
speaker  to  make  a  turn.  When  the  participants  give  their  turns  to  the  other,  they could  take  it  for  themselves  or  give  it  to  other  participant;  those  are  called  local
management system Yule, 1998: 72. Conversation  usually  runs  smoothly  because  the  participants  try  to
cooperate  by  understanding  the  local  management  system  or  a  set  of  unwritten conventions  in  conversation.  In  understanding  the  structure  of  conversation,
Kasper  and  Blum-Kulka  say  that  there  are  two  aspects  to  be  understood: mechanical aspect and linguistic aspect. The mechanical aspect could be presented
with  turn  taking,  and  linguistic  aspect  is  presented  with  adjacency  pairs  1993: 46.  Furthermore,  Levinson  1983:  303  describes  that  adjacency  pairs  is  part  of
local  management  organization  in  conversation.  Adjacency  pair  is  one  of  a  sign
that conversation is locally managed or done without any conscious plan because the patterns of adjacency pairs could organize the conversational floor or turn, and
make the participants know what to expect from the response which follows what they  are  saying.  Bloomer,  Griffths,  and  Merrison  argue  that  adjacency  pairs  are
related  to  turn-taking  mechanism  by  the  adjacency pair‘s  rule;  that  is  if  one  is
finished in producing the first part of adjacency pairs, then one should stop talking and gives opportunity for the next speaker to produce the second part 2005: 62.
Thus, adjacency pairs help the participants to know when the other participants‘
